This invention relates to paper cutters and more particularly to wrapping paper cutters used to tear or cut wrapping paper from rolls.

One object of this invention is to provide a new and improved wrapping paper cutter. Another object is to provide such a device having cutter means which is adapted for cutting paper of various widths. A further object is to provide such a device with a cutter which may be used with diiferent widths of paper and which may be readily arranged to cut the different widths 01 paper. Yet another object is to provide such a device which will remain'in adjusted position. Another object is to provide means for holding rolls of paper of difierent widths. A further object is to provide paper holders and cutters which are relatively extensible. Other objects and advantages of this invention will be understood by reading the following description taken in connection with the accompanying drawing.

In the drawing Fig. 1 is a view in side elevation of a device incorporating features of this invention. Fig. 2 is a sectional plan view taken on the line 2-2 in Fig. 1. Fig. 3 is a section elevation taken on the line 33 of Fig. 2. Fig. 4 is a detail view showing the upper paper roll engaging roller. Fig. 5 is a three-cornered perspective showing a slightly difierent detail of the cutter blade.

Considering the drawing, the device incorporating features of this invention comprises a base member l0 and an extensible upright standard II. The standard is arranged to carry an extensible cutter [2 which is arranged to rest against a roll of. paper [3 which latter is supported by the turntable l4 mounted on the base and the roller l5 carried at the upper end of the standard.

Considering the drawing in greater detail, the device is arranged to be mounted upon or secured to any appropriate supporting structure. The base If! comprises a substantially rectangular metal plate having a downwardly extending flange l6 and a plurality of downwardly extending protuberances l1, l8, l9 and 20. These protuberances are positioned adjacent the four corners of the base plate and have been shown with suction cups 2|, 22, 23 and 24 attached thereto. These cups are secured to the protuberances by the holding means, shown as machine screws 25. The base may be secured to glass or marble cases by the suction cups or it may be screwed to the counter or table using these same protuberances for the threaded connections. Two other protuberances, 2B and 21 extend downwardly from the plate, the former providing the bearing for the turntable l4 and the latter providing the point of securement for the upright standard I l.

The turntable I4 is provided with an upwardly extending boss 28 to be engaged by the center "5 opening in the roll of paper and with a downwardly extending boss 29 containing the bearing pivot 38. The pivot 3!] is arranged to extend into the opening 3| of the plate ill and to have its lower end 32 supported on a bearing plug 33 10 which is threadedly secured in the boss '26. In this manner, the turntable is rotatably supported upon the base plate and may be removed if the circumstances should demand such action. The turntable itself. has a plane surface'upon which the roll of paper is supported and has an overall configuration which is substantially oval in shape having irregular bulged ends 34 and 35 The upright standard H may comprise two or more telescopic members one ormore of which may be either solid or tubular in cross section. The lower tubular member 36 is arranged to pass through an opening 31 in the plate Ill which latter opening extends downwardly through'the boss 27. Q lar member in locked position. In order to provide a means for tightening the connection between the base plate and the tubular standard 36,

on occasion, if the latter should work loose, an

opening 39 is provided in the downwardly ex- 5 tending flange in the base plate. By means 'of this opening it is possible to insert a screwdriver to tighten the screw 38, especially when the base is secured by the suction cups or other means to the structure to which it is mounted. Another tubular member 40 is arranged to telescope within the member 36 so as to be relativelymovable with respect thereto. This latter member may be provided with a plurality of holes 4|, 42, etc., which are threaded for the reception of a screw i it which is arranged to pass through an opening 54 and a tubular member 46. In this way, the two parts of the standard are relatively movable and adjustable with respect to each other, but

they may be readily locked in adjusted position when a paper roll of definite width is to' be used. The machine screw 43 is screwed up tight to lock these parts together. It will be readily understood, however, that other means for securing these parts together may be used as, for instance,

a slot and bolt connection. At the upper endof the member 40 of. the standard is carried the roller 15.

The standard 49 extends upwardly having a horizontally extending part atthe outer end of A suitableset screw 38 secures the tubuwhich is secured the upper roller or turntable. The roller I5 is secured to the standard so as to have limited relative movement with respect to the turntable l4 when the two component parts of the standard are fastened together. A T shaped tubular member 46, which may have the inner walls 41 and 48 of the: cross part of the T and the leg part 49 split, is secured to the standard. A second tubular member 58 provides the bearing for the spindle 5| carrying the roller E5. The roller may be secured to this spindle in any appropriate manner,- having been shown as mounted on a small shaft portion 52, the end of which is upset at 53 to retain the roller on the shaft. It will be noted that the roller |5 is provided with a boss 88 which is arranged to cooperate with the lower boss 28 in holding the paper. Roller I5 is rotatably mounted on the shaft 52. At the upper end of the tubular bearing member is placed a plug 54 which serves as a fixed abutment for the yieldable spring 55, the opposite end of which engages the upper end of the spindle 5|. The spindle, being a relatively movable member, it is readily understood that the roller |5 may be moved a limited distance against the action of the spring, when placing a roll of paper into the device. To provide for a definite relative movement the spindle 5| is provided with a slot 51 of definite longitudinal extent. The pin or key member 58 is arranged to lock the T end bearing members together as well as to provide the means for limiting the longitudinal movement of the spindle 5|. This latter limitation of movement is accomplished by allowing the pin 58 to extend into the slot 51.

For the purpose of cutting the paper, the knife I2 is carried on the standard by means of two arms 60 and 6|, each of which is secured to the knife sections by appropriate fastening means at the points 62 and-63. The other ends of the arms engage the standard by the curved portion 64. Each arm is retained in engagement with the paper of the roll by means of a resilient element 66 having one end 67 secured by a bolt 68 to the standard 40 and the opposite end 69 being in engagement with the arm by means of the gripping portion 10. The corresponding yieldable means 1| is engaged with the lower standard 36 and the arm 6|. As a result of these connections, the paper cutter will always be yieldably urged against the roll of paper.

The extensible knife itself comprises a plurality of relatively slidable cutter elements, blades or members, by way of example two in number and indicated at 13, 14. As the elements 13, 14 are relatively slidable provision is had for increasing the length of knife to an extent greater than the length of a cutter element. The elements 13, 14 are arranged to fit together tightly and to be locked together by two or more fastening elements 18 and 71. These latter elements are arranged to lock the parts together by a threaded engagement with the threads in the holes 18 and 19. The knife may be tapered to cut and fit close to the paper roll as at 88, or along edge 98, depending upon the details of construction.

Other methods of securing the blades together may be used. For instance, the two portions of the knife l2 may be arranged as in Fig. 5, in the latter arrangement, knife I2 is composed of two metal members and BI each having a centrally formed ridge 82 and 83 respectively. The two parts of the knife may be put together with a snap action and can be arranged to lock in position with respect to each other by a series of two or more transverse complementary rib elements 84 and 85 on the members 8| and 85 and 8'! on the member 80.

The device illustrating the features of this invention has been shown in connection with a paper cutter of the upright type. It should be understood that the features of this invention are not limited to such a construction but are equally applicable in the structure of a horizontally extending cutter.
